6SH7/300B Specifications

 

GerusAudio 6SH7/300B


The Perfect amplifier for your 300B's

This amplifier uses a 6SH7's in Triode mode  for the input/driver. The 6SH7 is a low cost, high current valve that provides the right input sensitivity to drive the 300B, and using this valve only requires on coupling capacitor. The amp  is dead silent thanks to the low ripple B+ and DC heaters for the 6SH7’s  and 300B’s. There is no hum!
